Natural bristles are a type of material used in many different applications. They are made from the hair of animals, usually hogs, and are used for a variety of purposes such as cleaning, painting, and even medical procedures. The term 'AWN' is an acronym for 'animal-wool-nylon, ' which is a combination of animal hair and nylon fibers. Natural bristles are often used in brushes, brooms, and other cleaning tools due to their durability and strength. They are also used in medical procedures such as suturing and wound closure. Natural bristles are a popular choice for many applications due to their natural properties and ability to withstand wear and tear.
